What is BS EN 12101-8 – Fire resistance tests for smoke extraction ducts about?
BS EN 1366-9 focuses on fire resistance tests for service installations. The aim of BS EN 1366-9 ensures the correct installation and performance of the apparatus to avoid an emergency situation. BS EN 1366-9 is the ninth part of the BS EN 1366 series of standards specifies a test method for determining the fire resistance of smoke extraction ducts that are used for single compartment applications only. In such applications, the smoke extraction system is only intended to function up to flashover (typically 600 °C). This method of test is only suitable for ducts constructed from non-combustible materials (euro class A1 and A2-s1, d0). BS EN 1366-9 is applicable only to four sided and circular ducts. One, two and three sided ducts are not covered. This test has been designed to cover horizontal smoke extraction ducts intended for single compartment applications only. This test method of BS EN 1366-9 is applicable only to smoke extraction ducts that do not pass through into other fire compartments. It represents fire exposure of a developing fire (pre-flashover). For smoke extraction ducts that pass through into other compartments, the method of test described in BS EN 1366-8 should be used. The smoke extraction duct is part of the smoke extraction system which also includes smoke control dampers and smoke extr...
